trishs have only just got around to reading that article you kindly posted about historical child abuse in the BBC. Bit of a long rambling article but horrifying reading all the same.
I never much cared for Uncle Mac as a youngster. The voice on the radio I greatly loved was David Davis:

btw a famous story that I was told years ago about "Uncle Mac" is that, after the end of one broadcast, he gasped "Thank God the little b*ggers have gone!" Unfortunately the microphone was still live and his remark was broadcast.
But a paper from Monash University attributes a near identical story to George Saunders, "Uncle George" an Australian children's host, adding "there are numerous variations of the story (American as well as Australian) and it may well be apocryphal."
I guess not the George Sanders who starred in All About Eve.
